- LIQUID-POISON SPRAYER,

Application filed July 3,

T0 (ZZZ whom it may concern:

Be it known that I, NAPOLEON J. SALAD- INER, a citizen of the UnitedStates, residing at Bryan, in the county of Brazos and State of Texas,have invented a new and useful Liquid-Poison Sprayer, of which thefollowing is a specification.

The device forming the subject matter of this application is adapted tobe em: ployed for spraying liquid poison upon a standing crop, and the,invention aims to provide novel means whereby a center row, and rows onopposite sides thereof, maybe sprayed simultaneously, novel means beingprovided for manipulating the spraying members, and novel means beingprovided for securing air pressure in the tank on top of the liquidtherein.

It is within the province of the disclosure to improve generallyandtoenhance the utility of devices of that sort to-which the inventionappertains'. V

vAlthough a preferred embodiment has been shown, it will beunderstoodthat a mechanic, working within the scopeof what is claimed, may makechanges and alterations without in anywise departing from the spirit oftheinvention.

In the drawings :Figure 1 shows,in side elevation, a device constructedin accordance with the invention; Figure 2 is a top plan; Figure 3 is arear end elevation wherein parts are broken away, and wherein remoteparts are omitted; Flgure 1 1s a sectional detail illustrating thevalve; Figure 5 is a side elevation of the nozzle; Figure 6 is a planwherein the nozzle is viewed at right angles to the showing of Figure'5,

the nozzle being assembled with one of the flexible discharge tubes.

In carrying out the invention, there is provided a wheel-mountedvehicle, including a frame 1 provided at its forward end -with anysuitable draft means'2. Anaxle 3 extends transversely of the frame 1intermediate the forward and rear ends of the frame and is secured totheframe as tank 7 the support carrying a seat 10dis- 1924. Serial No.724,030.

posed about in vertical alinement with the axle 30.

Upstanding and rearwardly inclined standards 11 are mounted on theframerl at the rear end thereof, and may be con sidered as part of theframe. On the upper portions of the standards 11, a horizontal shaft 12is journaled in bearings 53, the shaft being equipped intermediate itsends with a crank 14. sprocket wheel 15 is loose on one end of the shaft12, a sprocket chain 16 being engaged with the sprocket wheels 15 and 6.The numeral 17 designates a clutch, operated by a lever 18 fulcrumed ona segment 19 carried by the standard 11 which is adjacent to thesprocket wheel 15, the lever having a latch end ofthe tank 7 Verticalguides 22 are; connected at their lower ends to the platform 21 and attheir upper ends to the tank 7, the guides slanting downwardly andrearwardly, as shown in Figure l. A pump cylinder 23 is secured to theplatform 21 and vis located between, and. sustained by, the

lower ends ofthe guides 22. From the pump cylinder 23, a conduit24extends to the upper front portion of the tank 7. The.

piston rod for the pump cylinder 23 is marked by the numeral 25 andcarries a cross head 26 mounted to reciprocate on the guides 22. Thelowe'r end of a pitman 28 l is pivoted to the upper end of the pistonrod 25, the upperend of the pitman being mounted on the crank 14% of theshaft 12.

and are provided at their inner ends with arms 30, pivotally mounted at31 011 the platform 21 in such a waythat the carriers may have acompound vertical and horizontal movement. A zig-zag'bracket 54 is secured to the rear end of the tank 7 and slants downwardly andrearwardly. 1 The bracket 5-1 includes substantially vertical arms 32,downwardly and laterally inclined arms 32 joined at their lower ends tothe lower ends of the arms 82, and converging arms 32, connectedtogether at their lower ends, and connected at their upper ends to thearms 32" of the bracket 54. The arms or extensions 30 of the sidecarriers29 are adapted Rigid tubular carriers 29' are supplied, 9 I

ends, with the con} to slide downwardly and outwardly on the tensions 50of the nozzles, is discharged rearparts 32, whereas the extension or armof the middle carrier is adapted to be guided downwardly by the arms 32of the bracket, into the central position shown in Figure 2. Passing tothe means whereby thecarriers 29 are raised and lowered, it will beobserved that, in Figure 1, a vertically movable lev r 33. is tulcrumedat 34: on the standard 11 which is adjacent to the sprocket wheel 15,,the lever having a loop-shaped 'i'oot 35,'the side portions of the footconverging as they extend downwardly. That end oi the too-t 35' which isremote from the lever 33 is pivoted at 36 to the standard it which isremote from the sprocket wheel 15 all of which will he understoodreadily when Figures 3 and l are compared. The lever 33 is equipped witha latch mechanism 37 adapted to cooperate with a segment 3 8 on thestandard 11 which is adjacent to the sprocket wheel A couplingcommunicates with the rear erfd of the tank 7, and in the coupling,casing 42 is interposed, a quick-closing alve being j ourna-lfed inthecasing, and having a stem 4% which is upw rd laterally inclined, thestem terminating in a handle i5 located near to the working ends of thelovers and 18. Flexible tubes it) extend through the rigid tubularcarriers 29 and are in communi-ation, at their inner ig- 39. Couplingsac are mounted in therear ends of the tubes 4'0 and receive the necks-elof the heads 48- of discharge nozzles, the neck 4-7 of each nozzlecarrying a screen ea. Each nozzle head e8 has a hollow spoon-likeeXtensionfiQ provided in its edges with ribs or slits 51. Col p-r'essionsprings 52 surround the ends of the tubes 46,. the inneren-ds'oi? thesprings ab ttiii'g againstthe ends oi the tabular carriers 29, and theouter ends'oi the springs abnttin-g against the nozzles, to hold them"in ,alinement with the carriers 29, as shown in Figure 1. I V

in practical operation, the lever 18 and "the chit-ch17 maybe operatedto couple the sprocket wheel 15 to the shaft 12, and, then,

'there is established an operating train for the pump, thetrainincluding one of the ground wheels 5', the sprocket wheel 6-, the

bhain l6, thesprocket wheel 15 the shaft 12', the crank 14, and pitrnan28, the piston rod 25 being caused to reciprocate in the-pump cylinder'23 and air being forced through the conduit- 2 i'into the tank 7, ontop of the liquid in the tank. The air pres sure thus attained forcesliquid in the tank through the casing 4&2 and the coupling 39, under thegovernance of the valve 43-, the valve being operated by means of thestem 44. The liquid proceeds from thecoup-ling 39- through the tubes 4cand, being dispersed through the slits 5-1 in the spoonelike exiy andwardly from the center nozzle, and laterally from the side nozzles, whenthe parts are arrangedas shown in Figure 2, a wide belt of standingplants thus being supplied with the liquid which is stored in the tank7.

The way in which the tubular carriers 29 are supported: by the bracket54-, when the machine is in operation, has been explained liereinbefore.Assuming that the carriers are arranged as shown in Figure: 2, it willbe obvious that when the lever 33 is swung downwardly at its forwardend, the loopshaped foot 3 5 of the lo- 1" will raise the carriers 29and tend to sw them togethertoward the longitudinal en tral plane-o lthe vehicle, the latch: mechanism 8-7 on the lever being engaged withthe segment 38 to hold the carriers 29 u'apl ii'ted. W hen the lever 33is manipulated toswing the foot 35 downwardly, the nozzle carriers 29'lowered, the parts 32 or the bracket 5d causing til' resicle carriers tolaterally and outv, as the parts 36' of the carriers traverse the c rrns3-2 of the bracket, the part 3-2" of the bracket carrying the centralmember 29 into a position inalinenientwith the loirgi rd inal medianplane of the vehicle, as shown: in Figure 2- I I claim" 1.
